Installation

2.1 Unpack and inspect
Procedure
1. Inspect the outside of the carton for any damage.
2. If damage is detected, contact the carrier immediately.
3. Inspect the hardware.
4. Make sure all the items in the packing list are present and in good
condition.
5. Notify the factory if any part is missing.
2.2 Install sensor
Keep ¼ in. (6 mm) clearance between electrodes and piping. The electrodes
must be completely submerged in the process liquid, i.e., to the level of the
threaded connection.
See Figure 2-1
If the sensor is installed in a side stream with the sample draining to open
atmosphere, bubbles may accumulate on the electrodes. Trapped bubbles
will cause errors. As bubbles accumulate, the conductivity reading drops. To
control bubble formation, apply a small amount of back pressure to the
drain.
